Torque Settings:
Effect of power settings and speed settings:
To accommodate different valves and other applications with different torque requirements, the actuator can be
set to apply different torque on the valve stem when in the seating mode. Please see table on pg. 4 to select the
power setting that is right for your application.
The actuator will use 100% of available torque to try and reach maximum speed. Current drawn will be limited
proportionally to the DiP setting applied actuator will automatically slow down and deliver the maximum available
torque for a given “Permanent Power Setting”.
Appendix
Calibration
The center position calibration routine can be initiated by switching Dip9 mome
ntarily “on” then “off”. This will
cause the actuator to go through a series of movements to determine the proper center position. This function is
useful if the actuators output gear gets manually rotated while the actuator is powered down and can’t properly
realign to the center by itself.
Troubleshooting:
Upon noticing a problem, your first step should almost always be to recalibrate the actuator by switching DIP 9 on
then off, all while the actuator is powered. This alone can solve basic problems. See section 3 on this page for
more details.
If the actuator does not move, try following these steps:
1)
Re-calibrate the actuator. This will move the actuator regardless of what signal it is receiving.
2)
A sticking valve may be the problem. Remove the valve from the actuator, and re-test the actuator.
3)
Remove power. Re-check the wiring and the power/signal apparatus. Power actuator, and re-calibrate. If
the problem persists, please call Hanbay for technical support.
Note: 66% setting and 100% setting may alter duty cycle:
Supply voltage needs to be min 14 VDC for 66% setting
- Supply voltage needs to be 16 VDC for 100% setting
- When operating above 20VDC and 66% power, Duty cycle is reduced to 50% - 25%
maximum.
At these levels, the electronics produce more heat which must be dissipated (depending on
environmental temperature)
